# Unreal Chemist vs PRIME 2.O

The clearest difference is ads: PRIME 2.O at none against Unreal Chemist's shown. Unreal Chemist's advantage is update cadence (every 2 weeks vs every 9 months) and device support (3 vs 1). On price and in-app purchases there is nothing between them.

Both are free to download. Unreal Chemist sells 1 one-off in-app purchase and PRIME 2.O sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Unreal Chemist ships an update every 2 weeks, PRIME 2.O every 9 months. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
